The tungsten basket heater must be operated in a vacuum environment to prevent rapid oxidation at 1800 °C. Use a power supply that matches the rated 5 V, 37 A, and 185 W to avoid electrical overload or damage.
- Vacuum requirement: Operate the heater only in a vacuum chamber to prevent oxidation of tungsten at high temperatures.
- Electrical matching: Verify the power supply delivers exactly 5 V, 37 A, and 185 W to avoid overheating or damage.
- Physical fit: Confirm the basket dimensions of 3.5 in L x 3/4 in W x 1/2 in H fit the source holder before mounting.
Follow these steps to safely install and operate the tungsten basket heater in a vacuum evaporation system. Confirm compatibility and electrical matching before applying power.
- Confirm geometry
Confirm the 1 wire x 0.040 in diameter geometry matches the source holder requirements. - Verify electrical rating
Verify the power supply delivers 5 V, 37 A, and 185 W to match the heater's electrical rating. - Check physical fit
Ensure the basket heater dimensions of 3.5 in L x 3/4 in W x 1/2 in H fit the vacuum evaporation source.
What power supply specifications are required to drive this tungsten basket heater at its rated 1800 °C?
The heater is rated at 5 V, 37 A, and 185 W. To reach its maximum temperature of 1800 °C, the connected power supply must be capable of delivering at least 5 V and 37 A continuously, with a power output of 185 W. Verify that your existing evaporation source supply matches these electrical ratings before procurement.
Will this 4-coil tungsten basket heater physically fit into a standard vacuum evaporation source holder?
The heater has a geometry of 3.5 in L x 3/4 in W x 1/2 in H and uses a single wire of 0.040 in diameter. These dimensions define the basket envelope and wire gauge for replacement matching. Confirm that your source holder accommodates these length, width, and height constraints, and that the wire diameter is compatible with your clamping or feedthrough design.
What are the handling and storage requirements for this tungsten basket heater to prevent damage before installation?
Tungsten basket heaters are fragile and should be handled with care to avoid deformation of the coils or wire. Store in a dry, clean environment to prevent oxidation or contamination. The product is available in packages of 5 or 10 pieces; order the appropriate package size to minimize handling of individual units and ensure spares are available for consistent evaporation runs.
This tungsten basket heater (1 wire x 0.040 in DIA, 4 coils) is rated for 1800°C at 5V/37A/185W, making it suitable for high-temperature vacuum evaporation of metals and dielectrics, but requires careful matching to the power supply and source holder dimensions.
Positive
- High-temperature evaporation capability: Rated for 1800°C, this tungsten basket heater enables high-temperature thermal evaporation of materials with high melting points in vacuum deposition processes.
- Clear electrical specifications for power supply matching: Specified at 5 V, 37 A, 185 W, the electrical loading provides a direct reference for matching the heater to the available power supply, reducing the risk of under- or over-powering.
Trade-offs
- Power supply and dimension compatibility verification required: The heater's electrical rating (5 V, 37 A, 185 W) and physical dimensions (3.5 in L x 3/4 in W x 1/2 in H) must be verified against the existing source holder and power supply before procurement to ensure proper fit and operation.
- Vacuum system dependency for intended use: Designed for vacuum evaporation source heating, the basket heater requires a compatible vacuum chamber and pumping system to achieve the low-pressure environment necessary for operation.
